摘要：Excessive copper can harm biodiversity and affect human health. Therefore, the remediation of copper tailings has become an urgent problem that must be solved. This study investigates the remediation effects of utilizing organic biological fertilizers and biological agents in conjunction with Broussonetia papyrifera restoration on copper tailings, as well as their impact on promoting B. papyrifera growth. This experiment conducted a quantitative analysis of copper tailings properties and copper components, examined the structure and stability of the bacterial community, and evaluated their influence on B. papyrifera growth. This study found that bioorganic fertilizer and biological agents could increase ammonium nitrogen content, improve the copper tailings quality index, and reduce residual copper content. The bioorganic fertilizer and biological agent treatment changed the copper tailings bacteria community structure, among which Thermodesulfovibrionia and Clostridioides were the core taxa. Although biological agents reduced the richness and diversity of the bacterial community, they were more beneficial to the stability of the bacteria community. Among copper tailings properties, pH was most closely related to the bacteria community. Bioorganic fertilizers and biological agents were found to increase the abundance of copper resistance genes, enhance fermentation function. Additionally, biological agents and organic biological fertilizers significantly boosted the B. papyrifera biomass by 122.59-329.40 % and increased the copper content in plants by 34.15-48.95 %. This study offers novel insights and a theoretical foundation for the future management of copper tailings.
